Display (Run) - Mode
After power up the relay is in display (Run) mode.
Scrolls the display to show one of the 10 possible values.
If a values exceeds the setting, the values is indicated flashing on inverted
display. In the case of a fault display the display always returns to the fault
value after pressing
. If voltage is missing on the measuring input
some values cannot be calculated and a no value is shown.
Input-Mode
The measurement is interrupted, the relays are in failure state and the
indicator LED has orange color

If the adjusted threshold of at least one measuring function is exceeded,
the corresponding relay output switches after the selected time delay tv
and the fault is indicated on the display.
Manual reset can be activated or de-activated and is operated with

Indicator output
Monitoring parameters can be set independently.
The MK9300N has 1 relay output.
The MH 9300 has 2 relay outputs.
Each monitoring function can be assigned to Relay 1 and/or to Relay 2. The
switching mode energized or de-energized on trip can be set in input mode.
